non-synchronousboostSEPICflyback85 V switchWQFN-16

LM51581RTER is a 16-pin wide-input non-synchronous switching regulator with an integrated 85 V power switch for boost, SEPIC, and flyback designs.

Best for

  • Wide-input boost converters
  • SEPIC power stages
  • Flyback power supplies

Avoid if

  • Applications requiring a synchronous rectifier
  • Designs exceeding the 85 V absolute maximum switch-node rating

Check before use

  • Peak inductor current versus current-limit tolerance
  • Maximum duty cycle at minimum input voltage
  • Switch-node transient voltage
  • PCB thermal layout and exposed-pad grounding
